Rust bindings for nvtx

[willkill07]

As the primary author of https://github.com/voltrondata/nvtx-rs, I wanted to potentially upstream/contribute the use of nvtx under Rust. If this is something that is not interesting at all or something that you do not want, then feel free to disregard or close this issue. If this is something that y'all would be interested in, I'd be happy to put forth additional effort in contributing this upstream here.

I'm unaware of the best packaging constructs for a mixed-language library, but nvtx-rs currently has this repository as a submodule which can easily be updated. To this end, it would be trivial to refer to relative directories if there is any interest in NVIDIA wanting rust language binding support. Currently, this is built off of the v3 branch rather than dev, so newly introduced bindings since the v3 release would need to be added as well.

Speaking only for myself (and not management or the company as a whole), I would be glad to accept your contributions, and I see no reason why we wouldn't want that. We will need to have some internal discussions about procedure and priority of this work. We will get back to you. Thanks for reaching out!
